Recent technological advancements encompassed under the Mobile Brain/Body Imaging (MoBI) framework, have produced exciting new experimental results linking mind, brain, and behavior. The main goal of the MoBI approach is to model brain and body dynamics during every-day, natural, real-life situations. However, even though considerable advances have been made in both hardware and software, technical and analytical conditions are not yet optimal. The MoBI approach is based on attaching synchronized, small, and lightweight neurobehavioral sensors to and around participants during behaviorally-measured structured, semi-structured, and unstructured settings. These sensors have yet to become fully unobtrusive or transparent. Even though a considerable technical and analytical gap still exists, acquisition of brain/body dynamics during real-world situations as well as in virtual, modified, and/or extended laboratory settings has been -in many cases- successful. Nevertheless, even if the technical/analytical gap is breached, novel hypotheses, measures, and experimental paradigms are needed in order to tackle MoBI’s ultimate goal: to model and understand cognition, behavior, and experience as it emerges and unfolds unto and from the world. Such a goal is not completely novel or unique to the MoBI framework; it is at the core of a long-standing scientific and philosophical challenge. The present work starts by briefly reviewing the historical origins of complexity in order to identify three “waves and ripples of complexity” derived from naturalist accounts to the historical brain/body problem. We furthermore argue for a current 4th wave. Finally, we offer the reader what we consider to be the main objective for the MoBI+4E framework in its quest for understanding the functional role of brain/body/world couplings in the emergence of cognition.

Owing to advances in neuroimaging technology, the past couple of decades have witnessed a surge of research on brain mechanisms that underlie human cognition. Despite the immense development in cognitive neuroscience, the vast majority of neuroimaging experiments examine isolated agents carrying out artificial tasks in sensory and socially deprived environments. Thus, the understanding of the mechanisms of various domains in cognitive neuroscience, including social cognition and episodic memory, is sorely lacking. Here we focus on social and memory research as representatives of cognitive functions and propose that mainstream, lab-based experimental designs in these fields suffer from two fundamental limitations, pertaining to person-dependent and situation-dependent factors. The person-dependent factor addresses the issue of limiting the active role of the participants in lab-based paradigms that may interfere with their sense of agency and embodiment. The situation-dependent factor addresses the issue of the artificial decontextualized environment in most available paradigms. Building on recent findings showing that real-life as opposed to controlled experimental paradigms involve different mechanisms, we argue that adopting a real-life approach may radically change our understanding of brain and behavior. Therefore, we advocate in favor of a paradigm shift toward a nonreductionist approach, exploiting portable technology in semicontrolled environments, to explore behavior in real life.

Adolescent use of amphetamine and its closely related, methylated version methamphetamine, is alarmingly high in those who use drugs for nonmedical purposes. This raises serious concerns about the potential for this drug use to have a long-lasting, detrimental impact on the normal development of the brain and behavior that is ongoing during adolescence. In this review, we explore recent findings from both human and laboratory animal studies that investigate the consequences of amphetamine and methamphetamine exposure during this stage of life. We highlight studies that assess sex differences in adolescence, as well as those that are designed specifically to address the potential unique effects of adolescent exposure by including groups at other life stages (typically young adulthood). We consider epidemiological studies on age and sex as vulnerability factors for developing problems with the use of amphetamines, as well as human and animal laboratory studies that tap into age differences in use, its short-term effects on behavior, and the long-lasting consequences of this exposure on cognition. We also focus on studies of drug effects in the prefrontal cortex, which is known to be critically important for cognition and is among the later maturing brain regions. Finally, we discuss important issues that should be addressed in future studies so that the field can further our understanding of the mechanisms underlying adolescent use of amphetamines and its outcomes on the developing brain and behavior.

Mental revolution starts from the education. Education is very important, as the strategic role of educations is to form children's mental nation. Development of culture and national character is realized through the area of education. Character development education is a continuous process and never ends (never ending process). As long as a nation exist, a character education must be an integral part of education over the generations. Implementation of character education should not be linked to the budget. It takes commitment and integrity of the stakeholders in the education sector to seriously implement the values of life in every lesson. Character education does not just teach what is right and what is wrong, but also inculcate the habit (habituation) of which one is a good thing. By doing so, students become acquainted (cognitive) about which one is good and bad, able to feel (affective) good value (loving the good/moral feeling), and behavior (moral action), and used to do (psychomotor). Thus, character education is closely related to the habit (custom) practiced and performed. Children do not need a curriculum, but a real life that support them. They learn from real life. What happens now, a lot of value or an existing teachings that are obscured, covered up with a lie that is packaged in an iconic form of advertising that is actually misleading.

Obesity is now epidemic worldwide. Beyond associated diseases such as diabetes, obesity is linked to neuropsychiatric disorders such as depression. Alarmingly maternal obesity and high-fat diet consumption during gestation/lactation may "program" offspring longterm for increased obesity themselves, along with increased vulnerability to mood disorders. We review the evidence that programming of brain and behavior by perinatal diet is propagated by inflammatory mechanisms, as obesity and high-fat diets are independently associated with exaggerated systemic levels of inflammatory mediators. Due to the recognized dual role of these immune molecules (eg, interleukin [IL]-6, 11-1β) in placental function and brain development, any disruption of their delicate balance with growth factors or neurotransmitters (eg, serotonin) by inflammation early in life can permanently alter the trajectory of fetal brain development. Finally, epigenetic regulation of inflammatory pathways is a likely candidate for persistent changes in metabolic and brain function as a consequence of the perinatal environment.

Chapter 6 explores the central concept of ‘investment’. It first considers the core question of the definition of ‘investment’ under the ICSID Convention and under investment treaties. It then takes up four important issues: (1) the time when an investment is made in relation to the temporal scope of the treaty protections; (2) the extent to which pre-contract investment may obtain treaty protection; (3) the place of an investment; and (4) the role of host State law in defining ‘investment’. It then analyses a set of problems that arise out of indirect investments: the relation between the losses suffered by a subsidiary in the host State and the investor’s investment; the rights of minority shareholders; claims brought by holding companies; corporate restructuring as a means to gain the advantage of investment treaties; the position of ultimate beneficiaries; and the position of portfolio investments.

Considerable progress has been made in understanding the role of autoantibodies in systemic vasculitides (SV), and consequently testing for anti-neutrophil cytoplasmic antibodies (ANCA), anti-glomerular basement membrane antibodies (anti-GBM), and anti-C1q antibodies is helpful and necessary in the diagnosis, prognosis, and monitoring of small-vessel vasculitis. ANCA-directed proteinase 3 (PR3-) or myeloperoxidase (MPO-) are sensitive and specific serologic markers for ANCA-associated vasculitides (AAV), anti-GBM antibodies are highly specific for the patients with anti-GBM antibody disease (formerly Goodpasture’s syndrome), and autoantibodies to C1q are characteristic of hypocomlementemic urticarial vasculitis syndrome (HUVS; anti-C1q vasculitis). The results of a current EUVAS study have led to changes in the established strategy for the ANCA testing in small-vessel vasculitis. The revised 2017 international consensus recommendations for ANCA detection support the primary use PR3- and MPO-ANCA immunoassays without the categorical need for additional indirect immunofluorescence (IIF). Interestingly, the presence of PR3- and MPO-ANCA have led to the differentiation of distinct disease phenotype of AAV: PR3-ANCA-associated vasculitis (PR3-AAV), MPO-ANCA-associated vasculitis (MPO-AAV), and ANCA-negative vasculitis. Further studies on the role of these autoantibodies are required to better categorize and manage appropriately the patients with small-vessel vasculitis and to develop more targeted therapy.

Reinforcement learning (RL) models have advanced our understanding of how animals learn and make decisions, and how the brain supports some aspects of learning. However, the neural computations that are explained by RL algorithms fall short of explaining many sophisticated aspects of human decision making, including the generalization of learned information, one-shot learning, and the synthesis of task information in complex environments. Instead, these aspects of instrumental behavior are assumed to be supported by the brain’s executive functions (EF). We review recent findings that highlight the importance of EF in learning. Specifically, we advance the theory that EF sets the stage for canonical RL computations in the brain, providing inputs that broaden their flexibility and applicability. Our theory has important implications for how to interpret RL computations in the brain and behavior.
